开发过程中会遇见很多应用注册时,需要通过手机发送验证码验证,这是可以封装一个验证码按钮:
attrs.xml
& lt; & # 63; xml version=" 1.0 " encoding=" utf - 8 " & # 63;比;
& lt; resources>
& lt; declare-styleable name=" VerifyCodeButton比;
& lt; !——默认背景——比;
& lt; attr name=" android:背景”/比;
& lt; !——点击后背景——比;
& lt; attr name==安慰肌?癱lickedBackground”格式比;
& lt; !——倒计时间——比;
& lt; attr name==罢?癱ountdownTime”格式比;
& lt; !——倒计时间后提示文字——比;
& lt; attr name==白址?癱ountdownText”格式比;
& lt;/declare-styleable>
& lt;/resources>
